Specification of Letters Patent. Patented Dec. 2, 19015.

Application filed March 20, 1915. Serial No. 15,829.

This invention has for its object to pro vide a simple and efiicientheater especially designed for heating the liquid contents of a tank orthe like.

Another object is the provision of a tank heater including a casingadapted to be partly submerged in a liquid to be heated and containing apreferred type of burner associated with a heating drum of hollowformation communicating with pipes extending through the casing.

With these and other objects in view, the invention consists in'thenovel construction, arrangement and formation of parts as will behereinafter specifically described, claimed and illustrated in theaccompanying drawing, which:

Figural represents a vertical central sectional view through the heater.Fig. 2 representsa top plan view thereof, partly in section.

Referring to the drawing in detail, wherein similar reference numeralsdesignate corresponding parts throughout the several views, the numeral5 indicates the casing of the heater which may be of poly onal orcylindrical formation, as desired, and includes an imperforate bottom 6and a removable top or cover 7. An air intake pipe 8 is securedexternally of the casing 5 and is provided with an angularly directedlower extremity 9 extending into and communicating with the interior ofthe casing whereby air is supplied to the burner. Air outlet pipes 10are arranged within the eas- 5 and communicate with apertures formed inthe cover 7 to permit the products of combustion to escape. A drum 11 ofhollow formation and preferably annular signed to conduct the water toand from the drum 11. The water inlet pipe 12 is arranged in a lowerhorizontal plane than the outlet pipe 13 so as to insure propercirculation of the water through the drum during operation of theheater. A burner 14 is supported upon the bottom 6 beneath the drum 11and is adaptedto be supplied with asuitable liquid fuel contained in thetank 15 by a fuel'pipe 16. Pairs of crossed and communicating waterpipes 17 are secured at their ends in the inner vertical wall of thedrum 11 and communicate with the water chamber 18 in the latter toaccelerate heating of the liquid contents thereof. A defieetor plate '19is arranged over the drum 11.

In use, the casing 5 is partially submerged in water contained within asuitable tank, not shown, in such position that the cover and air inletpipe 8 are disposed above the surface of the water. The water in thetank is admitted to the drum 11 through the inlet pipe 12 and isdischarged after it has been heated by the burner 14, through the pipe13, and thus the water contained within the tank is circulated throughthe drum 11 until thoroughly heated.

What I claim is:

A tank heater comprising a casing, a removable cover for said casing, anair pipe extending through the lower portion of said casing and upwardlyalong the side wall thereof, a burner arranged in said casing, a. fuelpipe supported in and extending exteriorly above said casing andconnected with said burner, a hollow annular drum disposed in saidcasing above said burner, outlet pipes for the products of combustioncommunicating with the interior of said casing near the bottom thereofand extending ANTON HERZINGER.
